T 0 all whom it may concern:

Be it known that I, CARL BARTELS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Safes or Vaults, of which the following is a specification.

This invention pertains to safes or vaults of round door type, and relates to improvements for causing the door to move squarely into and out of its seat, and to prevent the rotating of the door into improper angular position while itis out of the door-jamb, and to facilitate the adjustment of door-carrying mechanism to doors of uncutable manganese steel.

My improvements will be readily understood from the following description taken in connection with the accompanying drawings in which Figure 1 is a front elevation of a safe exemplifying my present improvements; Fig. 2 a front elevation of the door and crane-hinge, the doorbearing appearing in vertical section in the plane of line a. of Fig. 3: Fig. 3 a horizontal section of the safefront, door &c., in the plane of line b of Figs. 1 and 2: Fig. 4L a plan, mainly diagrammatic, of the hinge mechanism, the gear-disk having a portion appearing in horizontal section in the plane of line 0 of Fig. 2: and Fig. 5a horizontal section through doorparts, in the plane of line (Z of Figs. 2 and 3.

In the drawings :1, indicates the safebody, which may be assumed as an integral casting of manganese steel: 2, the tapering circular door-jamb in the front wall thereof: 3, the tapering circular door fitting the door-jamb and assumed as being a single casting of manganese steel: 4:, interrupted locking lugs on the periphery of the door, engaging behind similar lugs in the doorjamb: 5, the hinge-pivot: 6, the crane: 7, the door-bearing, in the form of a disk-like casing having in its central portion a large bearing with its axis coinciding with the axis of the door: 8, pintles uniting the door-bearing with the free extremity of the crane, the common axis of these pintles be ing parallel with the axis of the hinge-pivot on which the crane swings: 9, the gear-disk secured to the front of the door and having projecting outwardly from it a collared journal fitting the door-bearing: and 10, the pinion carried by the door-bearing and engaging teeth in the periphery of the geardisk to serve in rotating the door.

All of the parts thus far referred to may be of well known construction and subject to the usual variations in the form of those parts in safes of the character under discussion.

In safes of this character, with the doors held in the jambs by means of interlocking lugs of interrupted thread or interrupted lug form, when the door has been rotated to bring the door-lugs out from behind the jamb-lugs, the door may be moved outwardly and withdrawn from the jamb and swung to entirely open position. But, owing to the pivotal character of the crane-hinge, the door will naturally move out in the arc of a circle, instead of squarely, and the door is at liberty to rock on the pintles uniting it with the crane. The result is that, except with very cautious manipulation, the door, as it moves out, is apt to shift sidewise and strike the sides of the jamb, thus interfering with general smoothness of operations in opening the safe. The natural desire would be to have the door move smoothly outward free of contact with any jamb-parts the instant the outward motion started. The feature of my invention designed to take care of this matter will now be described.

Proceeding with the drawings :-11, indicates a plate of machineable metal firmly secured against the outer face of the door, between the door and gear-disk 9 12, screws securing the gear-disk to plate 11: 13, rivets cast integrally upon the outer face of the door and projecting through apertures in plate 11 and riveted upon the outside of the plate, it being understood that manganese steel, while uncutable, is capable of being upset and riveted: 14, a pintle at the base of the door-bearing forward of and with its axis parallel with the axis of crane pintles S 15, a fixed cam rigidly supported by the safe-body at the base of the crane-hinge, the surface of the cam starting at a given distance from the axis of hinge-pivot 5 and then curving outward and then becoming concentric with the hinge-pivot: 15 a horn around a portion of the cam and parallel with it, giving the cam a grooved form: 16, a Corrector-bar having one end pivoted to pintle 14, Fig. 4 showing a portion of this corrector-bar by a mere diagrammatic line: 17, the tail-end of the corrector-bar, the same sliding through the rotary hinge-pivot 5, in other words, the corrector-bar connects the door-bearing with the main hinge, but is capable of endw'ise motion relative to the hinge: and 18, a pin projecting from the corrector-bar into contact with the cam in such manner that as the corrector-bar swings on the axis of the hinge-pivot it will be moved endwise relative to that pivot.

Taking the parts as they appear in Fig. 3, or appear diagrammatically in Fig. t, the door is home in the jamb. Assume it to be turned to release the door-lugs from the jamb-lugs so that it is free to be withdrawn from the jamb. The opening motion of crane-pintle 8 will necessarily be the arc of a circle struck from the axis of hinge-pivot 5, and so also would be the path of outward movement of pintle 14 if the corrector-bar were simply pivoted to the hingepivot. But as pintle 8 swings outwardly in its arc, the cam, acting on pin 18, forces pintle 14 to the left, the result being that the door, instead of maintaining its normal relationship to a line cutting pintle 8 and hinge-pivot 5, has its inner portion moved somewhat to the right, or, more properly stated, it is prevented from moving to the left as it would naturally do. The result is that, notwithstanding the areal motion enforced by the crane the erratic motions of the inner portion of the door are corrected for and the door caused to move squarely outward and inward. The curvature of the cam is such as to maintain the proper correction of door motion until the door is so far out of the jamb that no fur ther trouble can occur. hen pin 18 shall have passed the extremity of horn 15 then the door may swing, in one direction, on cranepintles 8 to permit the open door to be put in some particular desired position. In other words, the cam is positive in controlling the door during a portion of the opening motion, giving freedom later.

Looking at Fig. 4, and assuming a line cutting the axes of pintles 8 and 14, that line may be viewed as a lever on the outer end of which corrector-bar 16 acts to pry the inner portion of the door to the right, or rather keep it from going to the left, as the door swings open. The corrector-bar is shown as being mounted at the base of' the hinged structure, but the correcting effect would be the same if it were mounted at. the top of the door, or at the top and the bottom, or at any place between the top and the bottom.

In opening a round door safe, the door is first rotated to free the door lugs from the jamb lugs, the free position being inclicated by some sort of a stop, in the present instance by the end of the toothed segment on the gear-disk being reached by the pinion. The door may now be pulled open, the door-lugs passing through the gaps in the jamb-lugs. If, when the door is but partially withdrawn, the door be accidentally turned, lugs may again engage and interfere with the opening operation. I provide against this. Again, when the door is open, if it gets accidentally rotated it will not enter properly into the j amb when it is desired to close it. I provide that the door can be turned only when it is home in the jamb.

Proceeding with the drawings :19, indicates a notch in the periphery of the geardisk: and 20, indicates a projection carried by the crane and lying just outside the outer face of the geardisk and in such position that when the door is rotated to bring the door-lugs into line with the gaps in the jamblugs, notch 19 will be opposite pr0jec tion 20.

hen the door is home in the jamb and turned to lug-engaging position, the notch and projection will be as seen in Fig. 2. Rotating the door, non-clockwise, brings the lugs to released position, and brings notch 19 in line with projection 20. Now, as the door begins to move outwardly, its corrected motion, as brought about by the cam, causes the righthand portion of the door to approach the crane, the result being that projection 20 quickly enters notch 19. This occurs early in the opening motion and be fore the rear door-lugs have passed to the front of the rear ja1nblugs, and after that the door cannot be rotated to cause lugs to engage while the door is being opened. hen the door is again closed and clear home in the jamb, the notch disengages from the projection and the door may be properly turned to bring about the proper engagement of lugs. In the example illustrated the notch is shown as being in the gear-disk, and the projection as being carried by the base of the crane, the projection on the crane entering the notch in the geardisk. The same effect would flow from a projection on the gear-disk or any other outside portion of the rotary door to engage a notch carried by the crane. In the construction illustrated the cam compels the door to approach parallelism with the crane as the door starts from its seat, and the projection and notch which look the door against rotation after the door has started out from its jamb are brought into action automatically as the door starts out. In the absence of the correcting device the projection and notch can be availed of, not automatically, of course but in a manner facilitating the opening and closing of the door. By practice one may swing the inner portion of the door to the right in pulling it open, thus putting the notch and projection into action, and when the door is swung back clear open the notch and projection prevent the acci dental turning of the door and keep it in condition for proper entry in the jamb when the door is to be again closed.
